Carbon composition resistors are made by mixing carbon particles with a binder molded into a cylindrical shaped, and then baked. Resistance decreases as temperature increases. Resistance is more prone to drifting than with other types.

Carbon composition resistors are made by mixing carbon particles with a binder molded into a cylindrical shaped, and then baked. Resistance decreases as temperature increases. Resistance is more prone to drifting than with other types. Standard 'classic' resistor. Sold in multiples of 5. 5% tolerance.

Carbon Film resistors are made by vacuum depositing a thin carbon film on a ceramic form. A good choice for applications which require a steady, low power drop. Sold in multiples of 5. Pricing is per pack of five (ie, entering 2 equals a total of 10 resistors)
